We are measuring the Iperf Throughput of CW9166 Radios for 6GHz Band with AP kept in Thermal Chamber.
We have 5G Client Laptop Connected. We measure the throughput between the 5GbE Wired Client (Iperf Server) and 6GHz Wifi Client (Iperf Client).
We see degradation in Iperf Throghput when thermal chamber is turned On and improvement in Throughput when chamber is turned off. The Wired Ethernet Statistics AP CLI command shows the input/output link rate difference.

The Chamber grounding is proper.. Ethernet Link rate in AP is degraded. How to debug further? Any debug trace shall be enabled to find the issue?
